nice
This tool is pretty nice and it has most of the things I wanted
from a file integrity verification system: constant datbases,
file attributes like inode, pemissions, number of links, uid,
gid, file size, access and modification times, and of course
SHA checksums. It's statically linked with OpenSSL and CDB,
so things don't get messed up if someone poisons your libs.
Very simple config file syntax (syslog.conf like) and checksum
generation for the current/known state database so you know
if it's been tampered with. See the homepage for more info.
